Daniel Craig wore one in QoS, just not CR.
The only reason Daniel Craig could get away with no cummerbund is because the buttoning point of his jacket was at his trouser band, so there would have been no white shirt showing.
However, most people couldn't pull it off as they probably aren't as fit as Daniel Craig and anyone who has love handles etc would ruin the line of the jacket.

Black tie isn't meant to be stylish, it's meant to be traditional.
I was in Ede and Ravenscroft today picking up a dinner suit and we had a lengthy chat about people who complain about cummerbunds, vents, peak lapels. He said if you're not willing to embrace the tradition of black tie, wear a black suit and a black necktie.
You can still have a well-fitting, traditional black ensemble. I'm a staunch advocate of cummerbunds/waistcoats.
